Groups contain a list of all departments within the organization. Groups define the organization’s hierarchical structure for timesheet approval, and each one can be broken down into subgroups. Each group is assigned a manager, and the manager of each group can view the timesheet of users in their group.
A group is defined on the Group Edit page (Setup > Organization > Groups > Group Edit).
Managers and Users can retroactively change a User's Group history so that the PSA data corresponds to the real world data.
Expense limits are set up at the Project level or the expense item level (not at the group level).
